Tunable magnetization relaxation of Fe_{2}Cr_{1-x}Co_{x}Si half-metallic Heusler alloys by band structure engineering
Shikun He, Yifan Liu, Yuhong Zheng +8
We report a systematic investigation on the magnetization relaxation properties of iron-based half-metallic Heusler alloy FeCrCo_Si (FCCS) thin films using broad…
Macro-spin Modeling and Experimental Study of Spin-orbit Torque Biased Magnetic Sensors
Yanjun Xu, Yumeng Yang, Ziyan Luo +2
We reported a systematic study of spin-orbit torque biased magnetic sensors based on NiFe/Pt bilayers through both macro-spin modeling and experiments. The simulation results show…
Varying temperature and silicon content in nanodiamond growth: effects on silicon-vacancy centers
Sumin Choi, Victor Leong, Valery A. Davydov +4
Nanodiamonds containing color centers open up many applications in quantum information processing, metrology, and quantum sensing. In particular, silicon vacancy (SiV) centers are…
Tunable Optical Coherence Tomography in the Infrared Range Using Visible Photons
Anna V. Paterova, Hongzhi Yang, Chengwu An +2
We report a proof-of-concept demonstration of a tunable infrared (IR) optical coherence tomography (OCT) technique with detection of only visible range photons. Our method is based…
Sub-100 nm Skyrmions at Zero Magnetic Field in Ir/Fe/Co/Pt Nanostructures
Pin Ho, Anthony K. C. Tan, S. Goolaup +5
Magnetic skyrmions are chiral spin structures that have recently been observed at room temperature (RT) in multilayer thin films. Their topological stability should enable high sca…
Quantum and classical dynamics of a three-mode absorption refrigerator
Stefan Nimmrichter, Jibo Dai, Alexandre Roulet +1
We study the quantum and classical evolution of a system of three harmonic modes interacting via a trilinear Hamiltonian. With the modes prepared in thermal states of different tem…
